SHED
SEALED HOUSING FOR EVAPORATIVE DETERMINATIONS
(Photo courtesy of Subaru)
Webber EMI manufactures a wide range of SHEDs in a variety of sizes, ranging from 10 cu-ft Micro
SHEDs to full sized Vehicle SHEDs capable of testing HD construction vehicles. Starting from one of
our standard configurations, a SHED can be designed to customer specifications with regard to size,
window placement, vehicle door type, and other performance or capability options.
All Webber EMI SHEDs incorporate a modular systems design that allows the basic Fixed Volume /
Fixed Temperature (FV/FT) enclosure to be upgraded to full Variable Volume / Variable
Temperature (VV/VT) enclosure. These upgrades can even be performed on-site, after installation.

(VV/VT) SHED. This SHED is
designed to support a full range of test
protocols and temperature profiles
between 45 ºF and 120 ºF. Using the
Webber EMI moveable roof system,
absolute SHED volume is
automatically controlled to maintain
zero-differential pressure between the
SHED interior and ambient laboratory
conditions. It is designed for testing
large equipment such as cars, trucks,
tractors and other large machinery

Running Loss SHED
The Webber EMI Model 106 Running
Loss SHED is a modified version of
our full-sized Vehicle SHED. This
extra long SHED, equipped with
special air handling equipment, a
proportional speed fan, vehicle
combustion makeup air, and an
auxiliary personnel door, is combined
with a centrally located dynamometer
to accept both front and rear wheel
drive vehicles. In addition to full
exhaust emissions testing capability,
this SHED supports all applicable
diurnal evaporative emissions test
protocols. (Photo courtesy of the California Air Resources Board)
On-Board Refueling & Vapor
Recovery
Webber EMI can provide On-Board
Refueling / Vapor Recovery (OR/VR)
capability for any of our SHEDs.
Using several different methods,
vehicles or other fuel-dependent
machines can be re-fueled while the
SHED is sealed.

All Webber EMI SHEDs are available as full VV/VT enclosures, or as
FV/FT enclosures that can later be upgraded to VV/VT capability.

Why choose a Webber EMI SHED?
Each Webber EMI SHED uses our exclusive ‘Ure-lok’ interlocking panel design, which serves to double the
sealing surface between each panel. Panels are held together by a patented mechanical interlocking system to
further increase sidewall rigidity and live load ratings. Each panel employs a chemically bonded cross-section
with an exterior surface of aluminum, an interior surface of type-304 stainless steel, and a 4” thick fire retardant
urethane foam core. The panels contain no organic materials (i.e., wood or other cellulose-based materials),
which can warp or naturally deform. All panel-mounted windows use triple-pane safety glass and are fully sealed
and trimmed inside and out. This ensures that all Webber EMI SHEDs have a durable and attractive exterior and
an easy to clean interior surface that is impermeable and non-reactive to both hydrocarbons and test fuels.
Webber EMI SHEDs can be fitted with either a top-hinged, tilt-up or vertical-sliding, ‘guillotine’ style vehicle
door. Vehicle SHEDs can also include a separate, side-opening personnel door. All door styles feature
pneumatic seals and triple-pane safety glass windows.
Every Webber EMI SHED structure fully complies with the leakage limits and HC retention requirements stated
in CFR 40 86.117-96. Additionally, the SHED structure is designed to safely withstand an internal-to-external
pressure differential of +/- 2 “H20 (+/- 0.5 kPa) without deformation or other negative effect.
In addition to our exclusive Moveable-Roof volume compensation system, Webber EMI is the only manufacturer
to offer a Mass-Flow Balance (MFB) orifice system, and a conventional ‘bag-based’ volume compensation
system. These systems are all designed to maintain a zero pressure differential relative to outside ambient
conditions across the SHED’s entire temperature range. While all three systems provide excellent accuracy and
repeatability, the Webber EMI Moveable-Roof system has been designed to eliminate the need for Tedlar bags or
other artificial devices to facilitate SHED expansion. By eliminating the ‘dead space’ typically required in a
‘bag-based’ SHED, the working volume of a Moveable-Roof SHED is reduced, thereby resulting in improved
testing accuracy – an absolute must for the new ‘zero evap’ regulations. Additionally, the Moveable-Roof system
provides precise feedback of SHED volume at ALL times during the test procedure, thus allowing for real-time
reporting of HC mass values.
Webber EMI SHEDs use dedicated, self-contained HVAC systems as standard equipment. Each system is sized
according to the SHED enclosure and the customer’s temperature requirements. In the case of VV/VT SHEDs,
the HVAC systems are capable of moving the SHED air temperature between 65 and 105 °F in approximately 1
hour. Custom systems are available to produce and maintain SHED air temperatures below 40 and above 140
°F. In all cases, Webber EMI SHEDs are capable of maintaining temperatures required for diurnal emission and
hot soak testing as described in CFR 40-86.117.96 and CFR 40 part 86 subpart B, respectively.
All Webber EMI SHED systems utilize a Windows-based, proprietary SHED data acquisition and control system.
This system is versatile, powerful and very user-friendly. It contains a menu of all pertinent U.S. EPA and
California ARB SHED test procedures, ready for immediate use. It also provides the ability to easily develop and
save custom test procedures for internal product development. This control system is capable of being used with
a variety of HC analyzers. In addition to the PC-based controller, Webber EMI SHED systems include a local
control panel, which allows for full manual operation of the SHED and various sub-systems.
All Webber EMI SHED systems are supplied with a number of safety systems such as a Low Explosion Limit
(LEL) detection system and pressure / temperature limiting switches. Optional safety equipment includes fire
suppression systems, retractable vehicle grounding straps, rotating light beacons, and audible alarms. All safety
systems are interlocked with both the manual and computer control systems to ensure safe operation.
Webber EMI SHEDs… recognized for their accuracy, durability, and quality… since 1975
